Coated substrates include a substrate coated with a coating composition comprising a metal oxide, a binder and optionally a mordant and a crosslinker for the binder. The substrate may be paper, such as commodity paper, and the metal oxide may be a fumed metal oxide or a colloidal metal oxide. The coating may be non-glossy and may be applied at a low coat weight. Methods for making coated substrates are also disclosed. The coating may be applied to the substrate during manufacture of the substrate, for example the coating may be applied to paper using a size-press machine during its manufacture.
Selon la présente invention, les substrats revêtus comprennent un substrat revêtu d'une composition de revêtement comprenant un oxyde métallique, un liant et facultativement un mordant et un agent de réticulation pour le liant. Le substrat peut être du papier, tel que du papier d'usage courant, et l'oxyde métallique peut être un oxyde métallique sublimé ou un oxyde métallique colloïdal. Le revêtement peut être non brillant et peut être appliqué en couché mince. L'invention concerne également des procédés de fabrication de substrats revêtus. Le revêtement peut être appliqué sur le substrat lors de la fabrication du substrat, par exemple sur du papier à l'aide d'une presse encolleuse lors de sa fabrication.
